3.Replaced the fuel filter with new one
4.Replaced the air filter with new one.
5.Maintaining the correct tyre pressure.
6.No rash driving only smooth acceleration and brakes.
7.Changed Engine oil and filter ,Gear oil and filter.
8.Removed, cleaned the Mass Air Flow Filter with Carb clean and refitted properly.
9.Lubricated all the linkages of accelerator cables.
10.Adjusted the recommended idle speed(760 +- 40 rpm)

The catalytic converter seems to be the only thing left to replace. If you really want to keep, and drive this car, replace the catalytic converter. If that doesn't cure it, you have a REAL problem.

7 kilometers per liter? That's 17 mpg....that's not bad at all for a 525i.
I don't think you have anything to complain about here....
